Could you compile apm.o as a module and post that?

AFAIK there is no way to copmpile APM as a module.
It needs to go in the kernel; however, then the
kernel will crash on many old desktops.

From Configure.help:

For 2.4.31 CONFIG_APM allows Y or M (module).

apm=off at boot time will disable the driver if it is built into the kernel. Not that newbies will know to do this.

From the internet:
cat /proc/apm with the computer unplugged from the wall is supposed to tell you a percentage (charge) and number of minutes.

Type apm -v (if the kernel has APM support - if not, it tells you so) for
a verbose message such as "battery status high 99% (1 day)".

If 2.2.26 does not support apm.o you could compile it into the regular kernel (or P1 kernel) as an alternate kernel for laptops with usable batteries.

"Newer" computers (starting in 1997) use acpi instead of apm and don't support apm well. Does kernel 2.2 also support acpi?

I have been turning off ACPI in BIOS - it made the IDE controller faster on one computer.
